20210333724 | ELECTROPHOTOGRAPHIC BELT AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - An electrophotographic belt in which bleeding of a cation component to the outer surface is suppressed after long-term storage after long-term repeated image output. The electrophotographic belt has a layer that includes a thermoplastic resin composition including a thermally melt-kneaded product of a thermoplastic polyester resin, a cation having a hydroxyl group, an anion, and a compound having at least two amide groups in one molecule. | 2021-10-28 |
20210333725 | IMAGE FORMING APPARATUS AND ADJUSTING METHOD - An image forming apparatus includes an image bearer, a transfer rotator, an adjuster, and circuitry. The image bearer bears a toner image. The transfer rotator contacts the image bearer to form a transfer nip between the transfer rotator and the image bearer. The transfer rotator transfers the toner image from the image bearer onto a sheet conveyed to the transfer nip. The adjuster adjusts at least one of a relative difference in linear velocity of the transfer rotator to the image bearer at the transfer nip and a relative contact pressure of the transfer rotator to the image bearer at the transfer nip. Based on a difference in image magnification, in a direction of conveyance of the sheet, of toner images transferred onto surfaces of one or more sheets conveyed to the transfer nip, the circuitry causes the adjuster to reduce the difference in image magnification. | 2021-10-28 |
20210333726 | DEVELOPING DEVICE USING TWO-COMPONENT DEVELOPER - An imaging system comprises a stirring-conveyance member to supply developer to a developing roller. The stirring-conveyance member includes a spiral structure to convey the developer and a reverse spiral structure disposed downstream the spiral structure in a conveying direction of the developer. The reverse spiral structure has a maximum outer diameter at an upstream end in the conveying direction and a minimum outer diameter at a downstream end in the conveying direction. The minimum outer diameter is approximately ⅗ or less, of the maximum outer diameter. | 2021-10-28 |
20210333727 | NIP ADJUSTMENT - In one example, a device comprises an image transfer member, a platen to form a first nip with the image transfer member, a photo imaging plate to form a second nip with the image transfer member, and a controller to determine first information relating to a characteristic of the first nip, and to determine second information for use in adjusting a relative position of the photo imaging plate and the image transfer member on the basis of the first information. | 2021-10-28 |
